My husband had a stroke a couple of years ago and a knee replacement 6 months later, Although he can walk (very slowly) he is quite week, especially in his knees and legs. Last night he fell off his bed, he was not hurt, but because of his week knees he cannot help himself up. He has osteo-arthritis, and suffers much back ache. So to pick him up on my own was a big mission as he is a dead weight. He has fallen before and most times I am alone with him. I am 69 years old, healthy but not very fit. How can I pick him up without hurting myself as well. We've tried using chairs for him to pull or push himself up but that does not help much.
